Why is the tree green?

Answer 1

It's dependent on the level of chlorophyll in the leaves plus any other pigments that are present to give natural colouring that evolution has deemed good for the longevity of the species. Evergreens tend to be darker as the needles (rather than leaves) are deisgned to reduce water loss through transpiration, so they have a smaller area through which to photosynthesise. trees 'retract' the cholorophyll in autumn before the leaves fall off, as it is expensive to make so they draw it back into the plant before the rest of the leaf falls off - that's why leaves go brown.

Answer 2

Trees are green because they contain a substance called chlorophyll. If I remember correctly, chlorophyll helps them absorb sunlight so that they can make natural sugars to feed themselves. I hope this answers your question! --A WikiAnswers user

Answer 3

Trees appear green because of a pigment called chlorophyll in their leaves. Chlorophyll absorbs red and blue light from the sun for photosynthesis, but reflects green light, giving leaves their green color.
